Bi.- FENNE- WALD, a citizen of the United States, residing. at Westphalia, in the county` of IOsage and State vof Missouri,-have invented new `and useful` Improvements in` s Automatic LHose-Couplings, of whichthe following is a jspeciication. i i

`This invention `relates to automatic couplings. and especially to couplings for the air 1 or `steam hose used on :railway cars.

2o` f umounting of av coupler `operating in the man- The object is to provide. a coupling comprising reciprocable member having connection Vwithfthe air line or steam line and mounted beneath the draw head of the `car s 'couplerproperin position to edectithe a'utomatic connectiony of the coupling members of the air or steamlinfe when the car cuplers are brought into operative position.

" A 'further object isrto provide forthe H ner specified, in order that it may have suitable lateral movement and in order that the y i s ihosecoupling 30 i permit of coupling members proper may also have the Pnecessary-movementsiwith reference yto the reciprocating portions of the coupling, to

the positive and automatic engagement .of theeconta/ctingplates of the i whenV thecars are in process of being coupledatogether. i

A stillfurther object is to provide novel locking means for the contacting plates of i the hose coupling members.

1 yOther objects will appear. fromthe following description taken in connection with the accompanying drawings, in which Y Figure `1 is a top plan view, with parts in section; Fig. 2 is a `view in side elevation;

"Fig 3 is a horizontal section; Fig. 4 is a rear elevation of lan apertured plate provided with an air port, and elements associated with the plate; Fig; 5 is a front elevation of The mounting means A pling memberswill first be described, and in "the plate; Fig. 6 is a section on line 6-6 of lilig. 2; Figs. 7 and 8 are diagrammatic views ofy the late locking devices, Fig. 9

shows a modi cation, in top plan and horizontal section. i chieiiy in elevation, may be regarded as (Figs. 4 and o although for the hose couthis'connection I provide a supporting member designated 10 which is pivotally mounted i t5 below the usual car coupler, the pivotal conneeton being shown at 12.` This member f ner described below.

Patenten ingr i9, 1919.

constitutes a guide for a "tubular air duct 14 which iS movable vlolngitudinally within member 10, said air duct 14 being rectangular in cross section if desired and having 60 connection at its inner end with the'` air hose forming a part of the air brake system. This connection is shown at 15. Acoiled spring 16 surrounds connection 15 and normally forces tubular member` 14 outwardly, being 65 compressed when the coupling membersfare brought into engagement ,upon the approach of the cars toward each other. l i.

The supporting member `18 constituting a rectangular frame embraces the member 110 70 and tube 114` near theiradjacent ends and retain the parts in proper position for effecting the coupling operationu Connected with portion 22 "of member lOls a socket member 23 secured at 24 and having connection with a rod 25 designed to operate the 80 locking-members of the coupler in the man- A tubular member is connected with air duct 14 and may have an opening therein substantially rectangularin cross section for 85 the accommodation of a similarly formed arm 32. Members 30 and: 32 are .curved to provide for theswinging movement of the. contactin plates of they coupler proper,

and within member 30 a coiled spring 36 is 90 `mounted to permit member 32 to have an inward movement and to cause saidmember to be forced outwardly `'when pressure thereon is relieved. This construction provides for movement due to the passage of carsaroun'd 95 curves. An engaging member 37? prevents the outward movement of arm 32 beyond a' given point.

The plates35- whichcontact with each other during the coupling.. operation and 100 which effect the connection between the scctions of the air line, are substantially dia` mond-shape in elevation` and are `provided with openings 39 closed ,b'yf means'` of valve members 40 mounted at 41. YThese plates 35 105 are pivotally mounted onY the offset end of the member` 14 by'meansof laterally Iextendfr 'ing ears 35 secured by pin 35. These valve members vhave projections 42 thereon,
